Blue Mussels

DEI is examining methods to expand production of cultured blue mussels by addressing the barrier to increased farmed mussel production in the northeast — seed production.

By improving hatchery production of juvenile mussels, DEI can provide reliable, cultured seed to growers who otherwise have had to rely on capturing wild seed (which is highly variable both in time and space) and are now limited to growing one mussel crop per year. If growers do not have to wait for wild spat to settle on their ropes, they can grow more than one crop per year.

DEI’s current research involves the following major components:

  • First time using cryopreservation on mussels: Cryopreservation is a method used for more cost efficient hatchery production of shellfish, but no methods currently exist for blue mussels. DEI’s is developing a protocol for cryopreserving mussel gametes and larvae.
  • Testing different types of settlement substrates in the hatchery and field: DEI is testing different types of rope to determine which is best on which to grow mussels.
